ABB has unveiled further details about its revolutionary Dynafin™ propulsion concept, which is poised to dramatically reshape maritime propulsion with enhanced energy efficiency, precision maneuverability, and clear emissions advantages for next-generation vessels.
Whale-Inspired Propulsion Principle
The Dynafin™ concept is inspired by the movement of a whale’s tail, representing a cycloidal-type propulsor that creates thrust and steering simultaneously. Unlike traditional ship propellers, Dynafin™ uses a large rotating wheel, powered by a main electric motor, operating at a moderate 30–80 RPM. Attached to this wheel are vertical blades, each individually controlled by its own motor and advanced control systems. The orchestrated motion of these parts produces both propulsion and remarkable maneuverability, allowing ships to efficiently adjust position and heading with unprecedented precision.
Efficiency and Performance Benefits
Independent studies from OSK-ShipTech confirm that vessels equipped with Dynafin™ can achieve up to 22% savings in propulsion energy compared to conventional shaftline systems, leading to substantial reductions in fuel consumption and emissions.
The gearless electric configuration eliminates many points of mechanical loss, and reduces vibrations and noise, thereby increasing comfort for passengers and crew.
Dynafin™ delivers superior maneuvering capabilities, making it optimal for ferries, offshore support vessels at wind farms, and luxury yachts.
Seamless Compatibility with Green Technologies
The fully electric nature of Dynafin™ makes it inherently compatible with both battery and fuel cell solutions, providing a clear pathway toward zero-emission shipping as maritime regulations tighten worldwide.
Its operational efficiency and minimal noise also align with stricter port and coastal area requirements, supporting global sustainable shipping goals.
Validated by Leading Institutions
Performance gains and technical claims for the Dynafin™ system have been independently validated by the Maritime Research Institute Netherlands (MARIN) and the VTT Technical Research Centre of Finland.
A New Era for Ship Design
Dynafin™ is particularly effective for small to medium vessels but marks a broader shift in how ships will be designed—enabling new hull forms and operational concepts that have not been achievable with conventional propulsion.
ABB’s Dynafin™ stands out as a pivotal innovation in marine propulsion, offering unparalleled gains in operational efficiency, flexibility, and sustainable operation for the years ahead
